A preparation method and use of a yellow fluorescent glass ceramic are disclosed. The preparation method includes: mixing a monomer, a cross-linking agent and a filling solvent evenly, then adding fumed silica and stirring evenly, further adding an ultraviolet (UV) photoinitiator and an UV absorber, and stirring thoroughly; adding a yellow phosphor (Y,Gd)AG:Ce, stirring thoroughly and defoaming to obtain a slurry; introducing the slurry into a mold, and curing by UV irradiation or three-dimensional (3D) printing to obtain a body; putting the body into a high-temperature furnace for heating to obtain a phosphor-embedded porous silica glass; putting the porous silica glass into a high-temperature vacuum furnace for densification and sintering to obtain a densified fluorescent glass ceramic; and finally cutting and surface-polishing.

Preparation method and use of yellow fluorescent glass ceramic

A preparation method and use of a green fluorescent transparent ceramic are disclosed. The preparation method includes: weighing, according to a stoichiometric ratio, elements present in CaCeAScBSiCO, in forms of oxides, carbonates or nitrates as raw materials; mixing the raw materials, annealing, melting at a high temperature, cooling and annealing at a low temperature; putting the glass into a high-temperature furnace, holding, raising the temperature, and performing crystallization and densification sintering; finally cutting, reducing and surface-polishing, where A is at least one from the group consisting of Lu, Y, Gd, La and Na; B is at least one from the group consisting of Zr, Hf and Mg; C is at least one from the group consisting of Al and P; x, y, z and m satisfy 0.001≤x≤0.06, 0≤y≤0.06, 0≤z≤0.06 and 0≤m≤0.3, respectively.
